Gillis, Los Angeies, Calif., assignor of fortynine percent to Sam Greenebaum, Los Angeles, Calif. Filed Mar. 29, 1967, Ser. No. 626,786 Claims. (Cl. 52-520) ABSTRACT OF THE DISCLOSURE A variable overlap, metal pan roofing construction for wood shingle roofs. A course of shingles carried on a metal plate. An anchoring clip for supporting a carrier plate and controlling the overlap or course spacing. Anchoring clips of various sizes for evenly covering any height of roof.

This invention relates to roofing construction and, in particular, to construction utilizing courses of metal pans with wood shingles or the like thereon.

My earlier Patent No. 3,232,020, entitled Roofing, issued Feb. 1, 1966, discloses a roof panel including a metal pan and a course of shingles mounted thereon, with the metal pan including means for engaging the lower preceding panel and the upper following panel. In this earlier construction, the spacing of each course is determined by the size of the metal pan. A problem is presented when covering a roof the height of which is not an even multiple of the predetermined pan spacing (taking into account the first and last course). A typical solution has been to make one special course with a different spacing, in order to complete the covering. However, this often results in an obviously irregularly spaced and unattractive roof.

It is an object of the invention to provide a new and improved roofing construction which retains the advantages of the earlier metal pan roofing panels, while providing for regular spacing in covering any size of roof. A particular object is to provide a roofing construction wherein the course spacing or overlap can be varied in order to achieve a visually uniform spacing and at the same time cover the roof regardless of height.

It is an object of the invention to provide a roofing construction comprising alternate rows of inter-engaging shingle carriers and carrier clips, with a clip overlying a carrier. A particular object is to provide such a construction which may include a number of clips with different lengths of carrier overlay permitting predetermined adjustment of course spacing.

It is an object of the invention to provide a new and improved roofing construction including a shingle carrier comprising a metal plate adapted to carry a shingle and rest on a roof supporting structure, and a carrier clip comprising an angle member having an upper portion for resting on the roof supporting structure and a lower portion overlying the upper edge of the carrier, with the clip and carrier having interengaging means for support of a carrier by a clip.

By way of summary, the invention comprises a variable overlap, metal pan roofing construction for wood shingle roofs including a metal plate for carrying a course of shingles and an anchoring clip for supporting a carrier plate and controlling the overlap or course spacing, with anchoring clips of various sizes for evenly covering any height of roof.

The invention also comprises novel details of con struction which will more fully appear in the course of the following description. The drawing merely shows and the description merely describes a preferred embodiment of the present invention which is given by way of illustration or example.

In the drawing:

FIG. 1 is a fragmentary top view, partially cut away, of a roof illustrating a preferred embodiment of the present invention;

FIG. 2 is a sectional view taken along the line 2-2 of FIG. 1;

FIG. 3 is an exploded perspective view showing the carriers and clips of the structure of FIGS. 1 and 2; and

FIG. 4 is a perspective view showing an alternative form of the clip.

In the drawing, the roofing construction of the invention is applied over conventional sheathing, indicated at 10. A plurality of shingle carriers 11, 12, 13 and a plurality of carrier clips 14, 15, 16 are illustrated, A shinglecarrier may be a metal plate, preferably with a right-angle bend 29 at the upper end thereof. Each shingle carrier is adapted to carry a plurality of wood shingles or other roofing elements and to rest on the roof supporting structure, such as the sheathing 10. In a typical form, each shingle carrier may be six feet in length with a course of shingles affixed thereto at the factory by stapling or by an adhesive or other suitable means, In an alternative construction, the shingles could be placed individually on the carrier after the carrier has been afiixed t0 the roof supporting structure.

Each carrier clip is an angle member, typically a length of sheet metal bent to a Z cross section with an upwardly opening groove 21 formed at the lower edge of the clip. The clips may be continuous in form, as illustrated in FIG. 3, or may be short as illustrated in FIG. 4, with a plurality of the short clips being used for each carrier.

In covering a roof, an eave starter strip 22 having a groove 21' is attached along the eave by nails 23. The first course with the carrier 11 is positioned at the bottom edge of the roof with the lower edge of the carrier 11 located in the groove 21. The carrier clip 14 is installed at the upper edge of the carrier 11 by nails 23, preferably with the central portion of the clip abutting the carrier. The lower portion of the clip overlies the carrier and shingles and functions as a retainer for the carrier and shingles. The shingles may be recessed along their'upper edges, as indicated at 25, to receive the overlying clip. The next course is positioned on the roof, with the lower edge of the carrier 12 engaging the groove 21 of the clip 14. Then the next carrier clip 15 is nailed in place. This installation procedure is repeated until the entire roof is covered, providing a complete metal covering on the roof under the wood shingles, with the nails under the shingles and with each course nailed at its upper end and retained and supported at its lower end by the clip. Flashing may be used under the nail heads if desired.

The spacing between courses, indicated as x on FIG. 1, is a function of the length of the lower portion of the carrier clip, indicated as y on FIG. 1. It is desirable to have the course spacing uniform over a roof surface, although slight variations in the spacing can be tolerated without affecting the uniform visual effect of the roof. Often, the height of a roof is not a multiple of the course spacing provided by a preformed panel type of construction. Under these circumstances, a compensating course has to be prepared on the spot, usually incorporated at the ridge, and resulting in one course with a great divergence in spacing from the remaining courses.

With the roofing construction described herein, the spacing required between courses to uniformly cover a roof can be determined in advance and clips having the required lower portion length can be selected for use in installing this particular roof. It has been determined that the desired objectives can be achieved by providing the roofing construction with three sizes of clips with halfinch intervals. If clips having a y dimension of 2 /2 inches, 3 inches and 3 /2 inches are available, a roof of any height can be covered with the metal pan construction described herein by selection of the appropriate clips. For example, if the roofer is using the clip with the 3 inch spacing and determines when he is five courses from the top of the roof, that he is going to be two and one-half inches over, he can use the 3 /2 inch clip for the five courses and come out exactly even. The half-inch dilference in course spacing will not be noticed visually. As another example, the roofer may note that when he is six courses from the top, he is going to come out three inches short. He can utilize the 2 /2 inch clip for his next six courses and make up the three inches. Thus it is seen that the roofer does not have to determine his course spacing prior to beginning installation of the roofing material. The roofer can start with the clip having the intermediate spacing and as he approaches the end of the job, make a precise measurement and choose the indicated clip for the remainder of the work.

Although an exemplary embodiment of the invention has been disclosed and discussed, it will be understood that other applications of the invention are possible and that the embodiment disclosed may be subjected to various changes, modifications and substitutions without necessarily departing from the spirit of the invention.
